Let's ramble!

Recently, my friend Rémi wrote on Twitter: “Why is it so long to get rid of Polio in the world? “, Did you know that there are barely 30 cases per year in the world! Only 3 countries in the world still have Polio cases. One of these 3 countries, Nigeria is on track to succeed with no cases reported since 1 year.

Should we worry about the anti-vaccine movement?

In the report on CNN twitted by Rémi, the specialist mentions that the number of children not vaccinated in the United States is growing continuously. Will we have to wait for another epidemic?

Surface disinfection against poliovirus type 1

According to Health Canada, in its guideline – Safety and Efficacy Requirements for Disinfectants Assimilated to Hard Surface Drugs, a broad spectrum virus is defined as:

Broad-Spectrum Virucide: A disinfectant that is shown to be effective against a representative, envelope-free and hard-to-kill virus, which is also intended to inactivate other enveloped and envelope-free viruses (ie a product of which A “broad spectrum virucide” efficacy has been demonstrated).

Also according to Health Canada:

The incidence of poliomyelitis in Canada declined following the creation of vaccination programs in the 1950s. The last indigenous case of wild poliovirus infection in Canada dates back to 1977. In 1994, the World Health Organization Officially declared Canada free from wild poliovirus. The cases of paralytic poliomyelitis that have occurred in Canada since then have been associated with imported cases of wild poliovirus infection and the use of OPV.

According to the MSSS, in its guide “Disinfectants and disinfection in hygiene and sanitation: fundamental principles”

Among the viruses are those that are enveloped by a lipid layer and those that are not. These are called naked viruses. Paradoxically, this lipid-rich envelope is easily altered by chemicals, making wrapped viruses vulnerable. In contrast, naked viruses are “accustomed” to coping with outdoor conditions and are more resistant to disinfectants. Generally, if a disinfectant is active against naked viruses, such as polio, it is likely to be active against enveloped viruses, such as AIDS (HIV).

Quaternary or sodium hypochlorite disinfectants

Quaternary or sodium hypochlorite disinfectants with the “broad-spectrum virucidal” claim are effective against naked viruses such as polio.
